3D echocardiography reconstruction of a right ventricle (green) with normal systolic function (end-diastolic volume 153 ml, end-systolic volume 64 ml, ejection fraction 58 %). The mesh is the right ventricle at end-diastole. The white areas are the pulmonary valve in the upper left side and the tricuspid valve in the upper right side. The right ventricular apex is towards the bottom. Data was processed with dedicated software (4D RV-Function, TomTec Imaging Systems).
